Torsion spring for electro-mechanical switches and a cantilever-type RF micro-electromechanical switch incorporating the torsion spring
摘要：
A torsion spring for an electro-mechanical switch is presented. The torsion spring comprises a set of tines including at least one tine extending from the free end of the armature of a switch. A terminus portion is rotatably suspended between the tines, and includes a conducting transmission line, at least a portion of which is exposed for electrical contact. The conducting transmission line has a length selected such that the exposed portion of the transmission line forms a circuit between the input and output of the micro-electro-mechanical switch when the micro-electro-mechanical switch is urged into a closed position, with the terminus portion rotating via the tines to form a conformal connection between the exposed portion of the conducting transmission line and the input and output of the switch, thus optimizing the electrical flow therebetween. The switch is also applied to MEMS devices.
摘要（中）：

提出了一种用于机电开关的扭簧。 扭转弹簧包括一组尖齿，其包括从开关的电枢的自由端延伸的至少一个齿。 末端部分可旋转地悬挂在尖齿之间，并且包括导电传输线，其至少一部分暴露以进行电接触。 导电传输线具有选定的长度，使得当微机电开关被迫进入关闭位置时，传输线的暴露部分形成微机电开关的输入和输出之间的电路， 通过齿旋转，以在导电传输线的暴露部分与开关的输入和输出之间形成共形连接，从而优化其间的电流。 该开关也适用于MEMS器件。
